Update: An earlier version of this post said it was the eastbound ramp. However, county officials provided the erroneous information online and via social media, but have since corrected it. It is the westbound ramp that will be closed.

Original post: The exit ramp from westbound Arlington Boulevard/Route 50 to Fairfax Drive will be closed from Wednesday, Feb. 29, through Friday, March 2.

The Virginia Department of Transportation will be installing new infrastructure as part of a project meant to improve Arlington Boulevard’s interchanges at 10th Street and Courthouse Road. There will also be lane closures on Arlington Boulevard in both directions between 10th and Rhodes streets; these will take place between 9 a.m. and 3 p.m. and will run through Friday as well.

This exit is one of the ways drivers can leave Arlington Boulevard and head to the busy Clarendon and Courthouse areas. Drivers can still use North Courthouse Road and 10th Street to exit Arlington Boulevard, but if you normally take either of those exits you should expect added congestion while the Fairfax Drive ramp is closed.

This $39 million dollar project will lead to other street closures in the area before its expected completion in October 2013. That will include closing the ramp from southbound 10th Street to eastbound Arlington Boulevard and Fairfax Drive and shutting down the ramp from eastbound Arlington Boulevard to Courthouse Road.
